Murphy's laws

Its as simple as it can get - google, copy and paste. That is all it took for this post. :)

Some Murphy's laws:

Any given program, when running, is obsolete.
If a program is useful, it will have to be changed.
If a program is useless, it will have to be documented.
If such a program has not crashed yet, it is waiting for a critical moment before it crashes.
Tell a man there are 300 billion stars in the universe and he'll believe you. Tell him a bench has wet paint on it and he'll have to touch to be sure.

When a man wants his wife to hear, she doesn't listen. When that same man doesn't want his wife to hear, she's all ears.
All the good ones are taken.
If the person isn't taken, there's a reason.
The nicer someone is, the farther away (s)he is from you.

Put in anything that you seem to know!
